BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent No. 374,840, dated December13, 1887.

Application filed March 10, 1887. Serial No. 230,342. (No model.)

.To all whom it may concern:

Be it known that I, THEODORE A. KooHs, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in BarbersChairs, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention has for its object to provide a simple and effectivedevice for adjustably locking thebaok andfoot-rest of a barbers chair onthe desired inclination; and it consists of the novel devices andcombinations of devices hereinafter described and specifically claimed.

In the accompanyin g drawings, Figure 1 represents a longitudinalvertical section of the barbers chair in its normal position or with theback and foot-rest in their vertical positions; Fig. 2, a similarsection of the chair with the back and foot-rest adjusted to occupy areclining position, and Fig. 3 a sectional plan 011 line 3 3 in Fig. 1,

Corresponding letters in the several figures of the drawings designatelike parts.

A denotes the seat-frame of the chair, consisting of the two sides,-each providing two legs, a and a, the upper side rail, b, and the lowerside rail, 0, the two sides being connected by the transverseseat-supporting rails d d, by the lower front cross-rail, e, and therear cross-plate, f. Between the front upper corners of the two sides ispivoted, at g, the pendent frame B, having at its lower end thefoot-board O. The pivot-pins g for frame B form part of metal sidepieces, D, of fancy shape-such as a swans neckwhich are secured againstthe upper edges of frame B and extend sufficiently upward for pivotallyconnecting therewith the front end of the armrest rails E, the rear endsof which rails are hinged to the side rails of the back F, beingpivotally secured with their lower ends between the rear upper cornersof the sides of seat-frame A. By this arrangement the armrests form theconnecting-links between the back and foot-rest of the chair, wherebythe swinging movement of either one will betransmitted to the other toassumea correspondingly angular position.

allow such rack-bar a limited vertically-slid ing movement, and coiledor leaf springs L, also secured against plate H, raise and hold suchrack-bar K on its elevated position, and thereby its teeth in engagementwith the teeth of the horizontally guided rack J. The treadle-bar Mbeing secured with one end against the forward end of plate H on a pin,1, it reaches rearward to the hind leg, at, of the chair, whence itextends downward to within ashort distance of the floor, with therearwardly-protruding treadle m to the end thereof. At about its middlethe horizontal portion of treadle-bar M is provided with anupwardly-projecting eye-lug, n, that is pivotally coupled with a centraldownwardly-projecting eye-lug, 0, of rack-bar K, in a manner that suchtreadle-bar M is suspended to such rackbar, and that both the rack-bar Kand treadlebar M are thus yieldingly supported by springs L.

To the. hub of rack J is pivotally secured by a screw-stud asocket-casting, p, for coupling the ends of two rods, 0 and I, havingeyed opposite ends that are pivotally coupled again with brackets q,rigidly secured against the opposite edges of the rear face of frame B,and for thus making the desired connections the rod 1? is placed on adiagonal position.

By stepping upon treadle m the barber will force downward the rack-barK, thereby disengaging it from the teeth of rack J, when he can freelyswing the back and therewith the foot-rest of thechair to the desiredreclining position, wherebythe rack J will be pushed v or pulled to movelongitudinally onits guidebar I to a corresponding position, and then byreleasing the treadle m again the springs L, by their elastic force,will raise the rack-bar K again to engage its teeth with the teeth ofrack J, thereby locking the back and foot-rest to retain their accordedreclining or upright position.

I am aware that barbers chairs have been known in which the back andfoot-rest have been operated by the horizontal movements of a longrack-bar and held at any point by the vertical engagement of a pawl orprojection acting upon the teeth or cogs of the rackbar, and I do notclaim such.

What I claim is- 1. The combination, witha barhers chair having abackand foot-board pivotal] y secured to the frame of the chair andconnected by the arm-rests for swingingsimultaneously, of rodsconnecting the foot-board with a short vertically fixed andhorizontally-movable rack, a rack-bar extending nearly or quite thewidth of the chair-frame and vertically movable and engaging with therack and coupled with a treadle, and springs yieldingly supporting suchrack-bar and pedal, all substantially as set forth, to operate asspecified.

2. In a barbers chair, the combination of the pivoted back and foot-restconnected to be moved and adjusted together, afixed guide- 25 rod, I,secured in the frame of the chair, a short sliding rack, J, movablethereon, and the connecting-rods O P,extending from rack J tofoot-rest,with thelongitudinally-fixed but vertically-movable rack-barK, springs for keep- 30 THEODORE A. KOCHS.
